Coralvue's new 10K is not as bright as Ushio, but does have more of a blue tint, so it would probably fall into the color you are looking for. Coralvue also has a 14K we need to get online, 59.95 price. Haven't looked at it yet, it might be too blue, since there bulbs lean more toward the blue spectrum.
Problem is these ratings seem all ove the place. For example 14K Aquaconnect is almost as blue as 20K Aqualine, so the numbers do not always show you how much blue tint you'll see.
thanks
